Somebody needs to beat this into the heads of union workers in the USA. They have been working under union contracts with maximum salaries regardless of the quality of their work for years - now immigration is going to lower those maximums close to the minimum.
The unions were destroyed by high oil prices and the political fallout which included the EPA and anti-coal/anti-nuke demagogues — energy costs went from low and stable to high and unstable — and foreign. Steel production went overseas, where labor costs were low and environmental ‘protection’ nil. Auto needed more expensive vehicles to cover labor costs, and that meant larger cars (Chrysler was the first US company to actually make money on a domestically produced subcompact, the Neon), which got lousy fuel economy — and ultimately the permanent change from 35 cents a gallon to $1 or more (and now, at 42 gal p bbl, $100+ a bbl, and 53 cents a gallon federal excise, $3 is the permanent floor) meant compact and subcompact cars from the Far East took over a large piece of the market (in the late 1950s, Chevy by itself was about 40 percent of the car business in the US).
